CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 307,457,- dated November 4, 1884.

Application filed June (i, 1884. (No model.)

5 and useful Improvements in Corn-Planters, of

which the following is a specification.

My said invention consists, principally, in certain improvements in the construction of the hopper andfeeding mechanism, whereby ro the several parts are more easily and quickly fitted and the cost of the machine thus lessened,

as will be hereinafter more fully described.

Referring to the accompanying drawings,

which are made a part hereof', and on which similar letters of reference indicate similar parts, Figure l is a side elevation of a cornplanter embodying my said invention; Fig. 2, a top or plan view of the hopper separately; Fig. 3, anunder side plan of said hopper;

2o Fig. 4, a vertical sectional view of the same looking toward the left from the dotted line e .e in Fig. 5 and upwardly from the same linel in Fig. 2; Fig. 5, a vertical sectional view looking to the right from the dotted line y y,

2 5 the cone and gearing being omitted; and Fig.

6, a detail section on the dotted line a: r.

In said drawings the portions marked A represent the framework of the planter; B, the driving-shaft; C, the hopper; D, the re- 3o volving feed-plate, and E a base-plate or outside rim in which the hopper is mounted.

IThe frame-work A, drive-shaft B, and other parts other than the hopperand feeding mechanism, are, or may be, of any suitable con-4 struction, and, as they form no part of this present invention, will not be particular] y described herein. y

The hopper C is preferably a cylindrical sheet-1n etal case, and has a east rim, C, secured Said rim has a downward ly-projecting flange, c, which sets down into the base-plate, as will be presently described. A cast shield-piece, `C2, is secured to the inside of the hopper directly over the hole in the base-plate, through which the corn drops,

and the kernels are thus prevented from dropping into said hole, except as they are fed in by the feeding mechanism. Said shield-piece extends down to the bottom of the hopper, except on one side, where an opening is formed @under the brush, not shown) between its lower edge and the top surface of the feedplate of sufficient size to allow the corn to pass under as the feeding mechanism carries it toward the hole. ,A brush, C, is also secured in the cylinder in front of the opening under the shieldpieee to keep back all the kernels except the one contained in the hole in the feed-plate, asis common in other planters. The ears c2, through which the bolt e3 passes to secure said shield-piece in position, are arranged, as shown, (see Fig. 6,) to come opposite the ears c on the rim C, and thus the bolts serve to hold both pieces in place.

The feed-plate D is in most particulars of substantially an ordinary construction, the flange d, extending up and adapted to fit around the flange c of the rim G, being the principal novel feature. Itis fitted onto the rim C upon the lower end of the hopper, as before indicated, and thus forms the bottom of said hopper. A gear-wheel, D, is provided upon its under side which meshes with a gear-wheel, B, upon the end ofthe drive-shaft l, whereby said feed-plate is driven. Said gear-wheel is preferably secured in place by lugs d, which fit into holes formed in the plate on each side ofthe bolt d2. Saidbolt extends down through the cone D2 and also through said gear-wheel, and thus holds them both tightly in position against the opposite faces of the plate l). Said cone D2 is mounted in the center of the plate and causes the seed to slide toward the row of holes di', which are formed in the edge of said plate. Itis provided with a downwardlyprol jecting flange, d, which extends down to the plate, where it engages with a corresponding circular fiange, di, and is thus more securely held in position. The base plate or rim E is also provided with an upwardlyprojecting flange, e, the upperedge of which is secured to the rim C by the bolts e', as shown. Said flange e is made somewhat larger than the flange c in order to leave sufficient space between them for the flange d of the feed-plate D to operate. Said plate or rim extends out under the feed-plate a sufficient distance to cover the holes cl3 therein and afford a suitable bearing therefor. hole, e2, directly under said row of holes cl3, through which the corn is dropped into the ground.

It is provided with a feed-- IOO The operation of my said invention is as follows: The several parts are secured in position as before described. The corn being then placed in the hopper the machine is set in operation. rlhe holes in the feed-plate are preferably of' a size a little larger than one seed, and thus one seed is carried around in them under the brush and shield-piece to the feed-hole e2 in the base-plate, where they are dropped one by one into the ground, as will be readily understood.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in a corn-planter, of the hopper C, having a cast rim, C, upon its lower edge, the feed plate D, having an upwardly-projecting flange, d, and the base-plate or rim E,also provided with an upwardly-pro- 2o jeeting flange, e, which fits around said flange the feed-plate and is secured to the riin C,

, said base-plate extending under the feed-plate a sufficient distance to cover the holes, and being provided with a feed-hole, e, substantially as set forth.

3. In a corn-planter, the combination of the hopper C,having a cast rim, G, upon its lower edge, the feed-plate D,n1ounted thereon, said feed-plate being provided with a gear-wheel, D', upon its under side and a cone, D2, upon its top, said gearwheel and said cone being secured to the opposite faces of said feed-plate by a bolt, d, and the base plate or rirn E, secured to the rini C outside of the edge of the feed-plate D, substantially as set forth.

4. In a corn-planter, the combination of the hopper C, the rini G, secured to its lower end, said rim having a downwardly projecting flange, c, the feed-plate D, having a gear-wheel, D', on its under side, and an upwardly-proj ecting flange, d, around its outer edge, said fiange d being formed to fit around the fiange c, and the base plate or rim E, said base-plate being provided with a iiange, e, which surrounds the feed-plate and is secured at its upper edge to the rini C', the feed plate D being thus provided with a suitable way between the riin C" and base-plate Ein which to run, substantially as shown and specified.

5. The combination ofthe feed.- plate D, gear-wheel D,having studs d, which enter holes in said feed-plate,the cone D2, and the bolt di, by which said several parts are secured together, substantially as shown and specified.

G. The combination ofthe feed-plate D,hav ing fianges d and d, and the cone D2, having flange d", substantially as shown and specified- In witness whereof I have hereunto set myy hand and seal, at Indianapolis, Indiana, this 2d day of June, A. D, 1.884.
